Abstract
The present invention concerns an analytical method that makes use of an oxygen-containing source having a predetermined content of an isotope of oxygen ZO, which is not the same as natural composition and distribution of oxygen isotopes, to detect and/or quantify oxygen in oxidizable compound(s).The analytical method allows detecting and/or quantification with relatively high precision and accuracy oxygen in oxidizable compound(s), even at low content. The method is easy to implement and can be used for in-line analysis.
